The experiences in the above forums are pretty similar to mine:
Velvia 50 - no problem at all (best Velvia film ever after the oiginal one now discontinued).
Velvia 100F - magenta casts depending on exposure or other random factors.
Velvia 100 - far less problems (but if I have to shot at 100 ISO I prefer Provia all the day).

G'day folks.
I was the writer of that post referred to above re a magenta cast in Velvia 100F. I'm still researching it and am very interested in scouting about for as many experiences of others with 100F as I can, hence landing on this forum when I caught a tag from Google...
One possible culprit I am looking at is the use of a Hoya Super HMC Skylight 1B filter which, as you'll know, has a light pink tint to it. I have noted there is no magenta cast in images shot with a polariser. My experience in recent times is that early morning sun on brown-ish coastal sand actually came out with a quite bizarre reddish tinge. I doubt though the cast is caused by lens coatings but my next point of scrutiny will be quality control of the E6 lab which, having been "over-run" by the new-fangled digital dictum, doesn't fire it up very often and when it does, it's a 6 day turnaround. Just want to check if they monitor their chemicals... On occasion I've had a greenish-blue cast on RVP 50 which my printer has deftly cancelled out during the Ciba process. So, for now, I will be re-running the shoot at the beach with a UV(0) filter and new roll of 100F from a different batch, and see what happens...

Example of obvious magenta cast but note absence of any tint to the whites of the water. Some may say a magenta cast can be beneficial for sunrise (this pic) and/or sunset, but only if the effect is moderate. This image is a travesty of the actual lighting observed.

Quoted so to show the image (because of the spam blocker PdJ).
I'm really curious about your finding, anyway I found out some magenta cast also in Velvia 50 if badly underexposed (more than 1 stop) and I also heard the same problem from other photographers here in Italy.

Alessandro ,
One point to note that while the cast was present under Skylight 1B filtration and not under polarisation (that is, POL exclusively, not piggybacked with 1B) is because a POL filter has a 'cooling' (blue) effect. The suggestion therefore is that the magenta hue is environmentally-influenced and the film, being red-sensitive, exaggerates it, just like that old chestnut Velvia 50 which is green sensitive and maxes out anything green.
Talking to a colleague this morning we touched on another, somewhat obscure subject of algal blooms on deposited salt in sand that react with sunlight and give rise to a very pink hue, often much loved by landscape photographers. Around 500km away we have a geological feature called "Pink Lakes" (dry saltwater lakes) where most nights in warmer weather the lakes literally glow vivid pink: a result of algal growth on salt crystals in the evaporated 'salt pans'.
Velvia 100F has delighted me on a 2006 trip to New Zealand with crisp, clear rendition (the rendition of whites and blues is marvellous) if a rather flashy, avant garde palette in hazy to bright sun. I'll continue to use it but watch for places where conditions may predispose to a magenta hue and change over to RVP 50 — or use a POL (not really suitable for ultra-wide angle landscape work).
Thanks for fixing up the photo; I was befuddled as to why it didn't show up!
